Specification of Letters Patent.

T cti/Z 1072/0777/ it may concer-n:

Be it known that we, EMERSON OARL and HARRY OoULs'roN, citizens of the United States, and residents of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have jointly invented certain new and useful Improvements in Valve Mechanisms, of which the following is a specification.

This invention relates to mechanism for operating a series of valves; and its primary object is to effect a sequential automatic operation thereof, while providing a ready manual control therefor, being adapted for use with mechanism for making inlaid fabrics, such as linoleum. l

In the accompanying drawings, Figure 1 is a top plan view, partially in section, in illustration of the invention. Fig. 2 represents an end elevation thereof. Fig. 3 represents a sectional view taken on the line 3 3 of Fig. 1. Fig. 4 represents a second position of part of the mechanism shown in Fig. 3. Fig. 5 represents a view of part of the belt-shifting mechanism. Fig. 6 represents a vertical sectional view through a pair of valves, and Fig. 7 represents a plan view of details of the stop mechanism. y

As shown in the drawings, a belt 1 is carried by a pulley 2, loose on the shaft 3, and is adapted to be moved into engagement with the pulley 4, fixed on the shaft. The belt is shifted by the fulcrumed lever 5, having the belt-engaging fork 6. The lever is operated by a link'7, connected thereto and to a fulcrumed lever 8, having a pin 9 working in a cam or angle slot 10 of a sleeve 11, the latter being fixed on a rocking shaft 12, operated by a crank 13.

Fixed to and rocked by the shaft 12 are the arms 14, connected by the links 15 to cams 16, the cams being fulcrumed on the levers 17 and bearing on the rocking levers 18 on the shaft 19. The levers 17 are provided with rollers 20, which ride on the cams 21, fixed to the shaft 22. This shaft has the spurwheel 23 fixed thereon and engaged by the pinion 24, flx'ed on the shaft 3, the wheel havingfour times the circumference of the pinion in the construction shown. The levers 18 make contact with valve-stems 25 and 25', working in the gaskets 26 and 26' and having the puppets 27 and 27', connected therewith, seated on the ports 28 and 28', the puppets being lifted by the levers and depressed by the respective springs 29 30 and 29' 30'. The ports 28 and 28' communicate with the respective chambers 31 and 31', the chambers being connected by the passage 32 and communicating with the respective ports 33 and 33', connected with the pipes 34 and 34'. The port 28' also communicates with the passages 35' through the gasket 26'.

The several cams 21 are so arranged on the shaft 22 that when the cams 16 hold the levers 18 elevated with reference to the levers 17 a roller 2O of a lever 17 will rest on the deepest part of one of the cams 21 and elevate one of the puppets 27, while the companion cam 21 has a-lower part in contact with the oorresponding roller 20, permitting the corresponding puppet 27' to remain closed. In this position of the mechanism communication is opened between a pair of pipes 34 34' by way of the corresponding port 33, chamber 31, port 28, passage 32, chamber 31', and port 33', and the pipe 34 charges into the pipe 34'. When the shaft 22 revolves the cams 21 through a quarter-revolution, the elevated puppet 27 closes its port 28 and the puppet 27' opens its port 28', permitting the pipe 34' to exhaust through the port 33', chamber 31', port 28', and passages 35', and simultaneously a second puppet 27 is elevated, while its companion puppet 27' remains closed to charge from a second pipe 34 through the valve connections therewith into the corresponding pipe 34'. In like manner the successive valves are opened and closed to charge and exhaust. The intermittent movement of the shaft 22, which causes the successive operation of the valves, is effected by the intermittent movement of the pulley 4, connected therewith by the shaft 3 and the gears 23 and 24.

The pulley 4 has thereon a boss 3'6, adapted for engaging a stop 37, pivotally supported by the links 38, having the fulcrums 39. The pulley is revolved by the belt 1 when the stop is withdrawn from engagement with its boss and held stationary at the completion of a revolution by the rengagement of the boss with the stop, whose restoration to its engaging position is aided by the counterweight 39', connected therewith.

A latch 40, having the fulcrum connection 41 with the stop and the pinv42, adapted to engage the notch 43 thereof, is provided witha IOO boss 44, which normally lies in the path of the pawls 45, pivoted to the levers 46, the latter having the fulcrum 47, on which they are oscillated by reciprocating rods 48. When a pawl 45 is moved backward, it is tilted and passes the boss 44; but when it moves forward its engagement with the boss is positive, and thereby the stop 37 is withdrawn from the boss 36, permitting the pulley 4to revolve. .As the boss 36 descends its shoulder 36' strikes and tilts the latch 40, disengaging the boss 44 from the engaging pawl 45 and permitting the stop 37 to be restored to position for rengaging the boss 36.

It will now be understood that when the shaft 12 is turned to shift the belt 1 into engagement with the driving-pulley 4 it simultaneously rocks the cams 16 to elevate the levers 18, by which the mechanism is operated and continues to operate until the shaft is reversed.
